A versatile recycled concrete rumble strip

Abstract

The invention discloses a new type of multi-functional rumble belt, which comprises a plurality of rumble belt monomers arranged and joined together by a mortise and tenon device along the width direction, a rubber cork, a heating cable, a high-frequency noise early warning device and a trapezoidal early warning device; The invention uses colored self-luminous recycled concrete to achieve the effect of easy identification for drivers, uses heating cables to achieve the function of melting snow in winter rainy and snowy weather, reduces the probability of vehicles rushing out of the road, and uses recycled concrete to actively respond to the national promotion of energy-saving and low-carbon technologies. It has the characteristics of convenient installation, low cost, resource saving, etc., and is suitable for long-term promotion and application.

Description

technical field [0001] The invention relates to the technical field of rumble strips, in particular to a multifunctional recycled concrete rumble strip. Background technique [0002] Rumble strips have proven to be an effective safety measure in reducing road departure accidents. According to research, the collision accidents caused by rushing off the road account for 64.4% of all collision accidents, and about 95.1% of the reasons are related to the driver. Further analysis also revealed that the main key causes of the accident were driver distraction, excessive steering compensation, poor directional control, excessive speed when cornering and drowsiness. According to the US Accident Analysis and Reporting System data, about 55% of fatal collisions can be reduced by the rumble belt. Furthermore, for two-lane roads in townships, this value increases to approximately 66%. [0003] Rumble strips are a relatively low-cost road safety measure. Economic analysis shows that th...

Problems solved by technology

[0006] (3) It is inconvenient to maintain during long-term use, and some rumble belts cannot be repaired;

[0007] (4) It requires professional mechanical personnel to operate, the efficiency is not ideal, and the quality is difficult to control;

[0008] (5) When the light is poor, vehicles may stray into the rumble belt, resulting in unnecessary noise;

[0009] (6) Part of the rumble belt is formed by destroying the road surface, which will cause water seepage on the road surface during construction and use, and lead to premature aging of the road surface

[0010] (7) It is impossible to remove snow and ice by itself in winter, and it needs to be cleaned by mechanical, manual or chemical methods (although the efficiency of mechanical snow removal is high, it cannot clean the thinner snow layer; the effect of manual cleaning is better, but the snow removal speed is slower and labor costs Higher; the chemical method uses snow melting agent to melt snow faster and has a better cleaning effect, but it will pollute the atmosphere and the soil on both sides of the road, destroy the ecological environment, corrode the road surface and facilities on the road, and reduce the service life)
